Congratulations to
Dr. Ravichandran’s1 team at the University of Virginia, who recently
published in Nature!
Their publication
found that during phagocytosis, macrophages release insulin-like growth factor
1 (IGF-1) and microvesicles. Once bound to its receptor, IGF-1 promotes uptake
of these microvesicles by the epithelial cells, leading to a decreased inflammatory
response. This was verified through classic airway hyperresponsiveness (AHR)
markers including increased eosinophils in the BAL fluid and increased airway
resistance after methacholine challenges.
In vivo AHR was assessed using the
flexiVent to both
deliver
aerosol challenges to the subject’s lungs and follow the developing
bronchoconstriction through automated data collection. The data generated can
be further partitioned to describe the contribution from the central airways
and tissues, which often offers additional insight into the mechanisms and
disease.
